The Carrier HT32BH850 Crankcase Heater is a critical OEM replacement part designed to maintain optimal oil viscosity in high-capacity HVAC compressors. Specifically engineered for 480V systems, this 70W resistive bellyband heater prevents refrigerant migration to the crankcase during the off-cycle, mitigating the risk of slugging and bearing washout at startup. Its low-profile, wrap-around design ensures maximum heat transfer to the compressor shell, keeping the lubricant warm and the refrigerant in a gaseous state. For field technicians, the HT32BH850 serves as a direct-fit solution for Carrier, Bryant, and Payne equipment, featuring high-grade lead wires and a robust clamping mechanism for reliable compressor protection in extreme ambient temperatures. Proper installation of this heating element is essential for extending the duty cycle of scroll and reciprocating compressors in commercial air conditioning repair and furnace maintenance applications.

Item is Non Cancelable / Non Returnable

• Prevents oil dilution by maintaining temperatures above the refrigerant’s saturation point.
• Ensures smooth compressor startup by reducing mechanical stress on internal motor components.
• Compatible with specific Carrier HVAC models, including 580FEV, 579FEV, and 558FEX series.
• Engineered for 480V 50/60Hz electrical configurations with a consistent 70-watt output.
• Direct OEM replacement (prev. part # CIAHT32BH850) ensures exact physical and electrical matching.

• How do I test the heater? Use a multimeter to check resistance across the leads; an "OL" reading indicates a broken element requiring replacement.
• When should the heater be energized? It must be energized at least 24 hours prior to initial system startup or after long shutdowns to boil off accumulated refrigerant.
• Where is it positioned? The band should be installed at the base of the compressor, below the oil level, making firm contact with the shell to prevent hotspots.
